Abstract
The utility model discloses a kind of seal ring, relate to Sealing field, comprise seal ring body, described seal ring body adopts soft rubber to make, in described seal ring body, ring is provided with projection, described seal ring body is provided with positioning hole and Mark Column, it is wear-resisting that described seal ring body surface is provided with one deck, corrosion resistant and resistant to elevated temperatures film, in the utility model, seal ring is wear-resisting because surface is provided with one deck, corrosion resistant and resistant to elevated temperatures film, thereby make close its application of having widened of rubber, extended its working life, the wear-resisting wiping of seal, abrasion resistance properties significantly improves, simultaneously, protruding can complete the effect of buffering, can effectively protect ring in seal ring to be without prejudice.
Description
Technical field
The utility model relates to Sealing field, is specifically related to a kind of seal ring.
Background technique
Seal ring, the circular cowling being comprised of one or several part, is fixed on lasso of bearing or packing ring and contacts or form narrow labyrinth clearance with another lasso or packing ring, prevents that lubricant oil from spilling and foreign object is invaded.Rubber seal of the prior art was used after a period of time, because rubber wearing and tearing, aging, spring force will there will be leakage after declining.Along with the time increases, ring wear increases the weight of to be out of shape rear rubber seal total failure with spring because of tired, corrosion., if Chinese application number is that CN 101949449 A disclose a kind of liquid pressure conduit pressure test seal ring, it comprises rigid backbone and rope made of hemp layer, described rigid backbone is evenly wound with rope made of hemp layer outward.Its long service life, cost is low, not bonding pipe, still, the non-refractory of this seal ring own, corrosion resistance are not strong, in applying it to the environment that high temperature or corrosivity are stronger, will greatly shorten its working life, increased the maintenance rate that uses equipment, simultaneously, interior ring is not provided with projection, easily causes the interior ring of seal ring impaired, the working life of having reduced seal ring.
Model utility content
The purpose of this utility model is to provide a kind of seal ring, to solve the above-mentioned multinomial defect causing in prior art.
A kind of seal ring, comprise seal ring body, described seal ring body adopts soft rubber to make, in described seal ring body, ring is provided with projection, described seal ring body is provided with positioning hole and Mark Column, and described seal ring body surface is provided with that one deck is wear-resisting, corrosion resistant and resistant to elevated temperatures film, and described Mark Column is rectangular box, long is 15-20mm, and wide is 10-15mm.
Preferably, the material of described projection is nickel alloy or rubber, is shaped as semi-circle, and radius is 2-3cm.
Preferably, described positioning hole is through hole, and radius is 1-3cm.
Preferably, described film material is Tungsten carbite or chromium carbide compounded material, and thickness is 5-10mm.
Preferably, described film sticks to this external surface of seal ring by glue, and glue composition is epoxy resin sealant, polyurethane sealant or esters of acrylic acid.
The utility model has the advantage of: because seal ring body surface is provided with that one deck is wear-resisting, corrosion resistant and resistant to elevated temperatures film, thereby widened its application, extended its working life, the wear-resisting wiping of seal, abrasion resistance properties significantly improve, film sticks to this external surface of seal ring by glue, film can be changed after using a period of time, and the film more renewing only need to stick to seal ring body surface with glue again, easy to use, quick; Simultaneously; protruding can complete the effect of buffering; can effectively protect ring in seal ring to be without prejudice; described positioning hole is through hole; radius is 1-3cm, and seal ring can accurately be located, and date of manufacture, specification and the operation instruction of seal ring indicated in Mark Column the inside; person's proper operation easy to use, has further improved the stability in use of seal ring.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of seal ring described in the utility model.
Fig. 2 is the sectional view of a kind of seal ring described in the utility model.
Wherein: 1-seal ring body, 2-film, 3-positioning hole, 4-projection, 5-Mark Column.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
As depicted in figs. 1 and 2, a kind of seal ring, comprise seal ring body 1, described seal ring body 1 adopts soft rubber to make, in this 1 body of described seal ring, ring is provided with projection 4, described seal ring body 1 is provided with positioning hole 3 and Mark Column 5, it is wear-resisting that described seal ring body 1 surface is provided with one deck, corrosion resistant and resistant to elevated temperatures film 2, described Mark Column 5 is rectangular box, long is 15-20mm, wide is 10-15mm, due to seal ring body 1 surface, to be provided with one deck wear-resisting, corrosion resistant and resistant to elevated temperatures film 2, thereby widened its application, extended its working life, the wear-resisting wiping of seal, abrasion resistance properties significantly improves, film 2 sticks to seal ring body 1 outer surface by glue, after being used a period of time, film 2 can change, 2 needs of film that more renew stick to seal ring body 1 surface with glue again, easy to use, fast, meanwhile, protruding can complete the effect of buffering, can effectively protect ring in seal ring to be without prejudice, described positioning hole 3 is through hole, radius is 1-3cm, and seal ring can accurately be located.
It should be noted that described protruding 4 material is nickel alloy or rubber, be shaped as semi-circle, radius is 2-3cm, and 4 effects that can complete buffering of projection can protect ring in seal ring to be without prejudice effectively.
In addition, described positioning hole 3 is through hole, and radius is 1-3cm, and seal ring can accurately be located.
In this example, described film 2 materials are Tungsten carbite or chromium carbide compounded material, thickness is 5-10mm, described film 2 sticks to seal ring body 1 outer surface by glue, glue composition is epoxy resin sealant, polyurethane sealant or esters of acrylic acid, thereby widened its application, extended its working life, the wear-resisting wiping of seal, abrasion resistance properties significantly improves, film 2 sticks to seal ring body 1 outer surface by glue, after being used a period of time, film 2 can change, 2 needs of film that more renew stick to seal ring body 1 surface with glue again, easy to use, fast.
Based on above-mentioned, in the utility model because seal ring body 1 surface is provided with that one deck is wear-resisting, corrosion resistant and resistant to elevated temperatures film 2, thereby widened its application, extended its working life, the wear-resisting wiping of seal, abrasion resistance properties significantly improve, and film 1 sticks to seal ring body 1 outer surface by glue, after film 2 is used a period of time, can change, 2 needs of film that more renew stick to this 1 surface of seal ring with glue again, easy to use, quick; Simultaneously; protruding can complete the effect of buffering; can effectively protect ring in seal ring to be without prejudice; described positioning hole 3 is through hole; radius is 1-3cm, and seal ring can accurately be located, and date of manufacture, specification and the operation instruction of seal ring indicated in Mark Column 5 the insides; person's proper operation easy to use, has further improved the stability in use of seal ring.
As known by the technical knowledge, the utility model can be realized by other the embodiment that does not depart from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, and is not only.All changes within the scope of the utility model or within being equal to scope of the present utility model are all included in the utility model.
